DRAFT AND STEERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 731,875, dated June 23,1903. Application filed February 3, 1903 Serial No. 141,656. (No model-lTo all whom it may concern:

I This invention relates to improvements in draft and steeringdevicesfor plows and similar implements in the use of whieh a straightcourse is desiredsnch, for instance, as in plowing up beetsthe objectbeing-topmvide a draft and steering mechanism so connected to a plowthat the plow-beam is relieved of all strain except a slight lateralstrain, thus making it more durable, and, further, to so arrange thesteering mechanism that the steering may be accomplished by very littlemanual exertion.

We will describe a draft and steering device embodying our invention andthen point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a portion of a plow with a draft andsteering device embodying our invention attached thereto.

Fig. 2 is aside elevation thereof; and Fig. 3 1s an inverted planview,part1y in section, on

the line 3 3 of Fig. 2.

Referring to the drawings, 5 designates the plow-point, 6 the standard,and 7 the beam. A draft-rod 8 has swinging connection with the beam bymeans of a clevis 9. This draft rod extends along and underneath thebeam, and its forward end is supported in a loop 10, adjustablyconnected to the forward end of the plow-beam.

As here shown,the upwardly-disposed members ofthe loop are slotted toreceive a clamping-bolt 11, which passes through the beam. A doublecrank has swinging connection with the forward end of the beam. Thiscrank consists of a vertical portion 12, having hearings in plates 1314, extended laterally from the beam, and the lower member 15 of thecrank is connected, by means of a link 16, with the draft-rod 8. Thedraft-rod is provided with a series of holes, as is also the lowermember 15 of the crank, so that the leverage may be adjusted by shiftingthe link 16. From the upper member 17 of the double crank a shifting rod18 extends to a lever 19, pivoted on the rear end of the beam. The uppermember 17 of the crankis also provided with a series of holes, so thatthe rod 18 may be adjusted to or from the vertical portion12. By thisconstruction there is comparatively little strain on the plow-beam, andby means of the lever 19 the draft-rod may be quickly shifted, so as tobring the plow into the desired course, and it is obvious that byplacing the operating mechanism near the forward end of the draft-rodvery little manual exertion will be required to shift it.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- In a plow or similar implement, thecombination with a beam and standardof a draftrod having vertical andhorizontal swinging connection with the standard below the beam,

an adjustable loop on the forward end of the "beam through which saidrod passes, plates extended laterally from theforward end of the beam, adouble crank having hearings in said plates, a link connection betweenthe lower member of the crank and the draftrod, a lever at the rearportion of the beam, and a rod connection between said lever and theupper member of the crank.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
